Sep. 2, 2014  Magnetic substorms, the disruptions in geomagnetic activity that cause brightening of aurora, may sometimes be driven by a different process than generally thought, a new study ... read more

June 9, 2014  Space is not empty. A wind of charged particles blows outwards from the Sun, carrying a magnetic field with it. Sometimes this solar wind can break through the Earth’s magnetic field. Researchers ... read more

Oct. 11, 2012  Scientists have developed a method to simulate gigantic magnetic fields that normally occur on neutron stars only. The physicists show that when small particles in complex plasmas are set into ... read more

Sep. 4, 2001  Space physicists predict gusty winds for the next few months at the Sun's north pole, an area that will be observed when the Ulysses spacecraft passes over it starting on Aug. 31. This pass over ... read more

Feb. 26, 2008  Astronomers have discovered that the sun-like star tau Bootis flipped its magnetic field from north to south sometime during the last year. It has been known for many years that the Sun's ... read more

Mar. 12, 2015  Identifying liquid water on other worlds, big or small, is crucial in the search for habitable planets beyond Earth. Though the presence of an ocean on Ganymede has been long predicted based on ... read more

June 9, 2011  Observations from NASA's Voyager spacecraft, humanity's farthest deep space sentinels, suggest the edge of our solar system may not be smooth, but filled with a turbulent sea of magnetic ... read more

May 2, 2011  Our Sun experiences regular eruptions of material into space, but solar physicists still have difficulty in explaining why these dramatic events take place. Now scientists think they have the answer: ... read more

Nov. 19, 2014  The sun may be playing a part in the generation of lightning strikes on Earth by temporarily 'bending' the Earth's magnetic field and allowing a shower of energetic particles to enter ... read more

July 30, 2015  Some of the most breathtaking views in the Universe are created by nebulae -- hot, glowing clouds of gas. This new NASA/ESA Hubble Space Telescope image shows the center of ... read more

July 30, 2015  Comet Churyumov-Gerasimenko poses new riddles: Surface material measurements performed by the Philae landing module indicate that the near surface material might have changed ... read more

July 29, 2015  Physicists have revealed a new understanding of nucleosynthesis in stars, providing insight into the role massive stars play in the evolution of the Milky Way and the origins ... read more

July 28, 2015  A group of scientists have described developing and launching their imager, which centers on "Lobster-Eye optics," as well as its capabilities and future applications in space ... read more
